The Seaward 42 is based on the Seaward Nelson 42 pilot boat hull design and is an RCD Category A ocean-going motor yacht at the top of the Seaward range. Typically, they are custom built to the owner’s requirements with a wide choice of layouts. The hull is the same as the well-proven all-weather Nelson pilot boats in use professionally around the world but with the addition of an integral stern platform to maximise the running length of the hull and contribute to ease of trim, handling, and sea kindliness.
The standard twin propulsion engines and drives are a pair of Yanmar 8LVs diesel engines rated at 370hp, but there are other options. These include the Cummins QSB 6.7’s rated at 425hp and the Yanmar 6LY-CRs, rated at 440hp. The engines are controlled by an electronic shift and monitoring system. The port and starboard gearboxes are arranged for handed rotation, driving outward turning 2” shafts and Seaward’s optimised 24″ 5 blade propellers, reducing noise and vibration and increasing efficiency. The large rudders are heavy-duty and the same as used on the pilot boats. They are of aerofoil section in cast bronze controlled through an hydraulic steering system.
